Ongoing Straight wire case- Class I skeletal same case, question N-2 Upright molars?

Same case - Ongoing Straight wire case- Class I skeletal The case is going well, most of the teeth look well align both upper and lower arch. Patients is happy:) Except, 1.8 and 2.8 did not made much progress. What would be the best approach to fully upright those molars? Would it be possible to expose the furcation if I use vertical elastics with lingual buttons for a few days, to help fully upright ? Considering that, these are wisdom molars which are smaller and have shorter roots. These teeth will replace missing second molars. Would it be better to continue with 018 NiTi DLx for another moth and use vertical elastics with lingual buttons to fully upright third molars? Or Move to the next .019 x .025 V-Force 3 wire and start closing the gaps? Same situation on the Left side.
